Phase Changes of Water
A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....
Curated OER
States of Water
Students investigate the 3 states of matter. In this physical science "matter" activity, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on...
Curated OER
Melting and Freezing of Water
Students examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

"I'm Melting!"
Third and fourth graders engage with a worksheet designed to help them differentiate between melting and dissolving. After reading an informative paragraph about the two actions, they consider four scenarios, and choose whether they...
University of Georgia
Freezing and Melting of Water
Examine the behavior of energy as water freezes and melts. An engaging activity provides a hands-on experience to learners. Collaborative groups collect data and analyze the graphs of the temperature of water as it freezes and then...
Curated OER
Water 1: Water and Ice
Students experiment with states of matter with water and ice. In this states of matter lesson, students experiment to discover what happens to water as it freezes to become a solid, ice. They observe what happens when ice melts back to...
Curated OER
Water and Ice
Students explore water and how it changes forms. In this investigative lesson plan students participate in an activity that shows them how water changes form and what it looks and feels like.
Curated OER
Water 3: Melting and Freezing
Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

How Can Freezing Make Something Warmer?
Crazy fact—freezing liquid actually gives off heat! Young scholars investigate the transfer of energy when liquids freeze using a chemical heat pack. The heat pack gives off heat as its liquid core freezes.

Molar Heat of Fusion for Water
How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third activity of the series, learners conduct an experiment, demonstrating the flow of heat...
Curated OER
Water and Ice
Students observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.
Curated OER
Physical Changes to Matter
Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...
Center for Learning in Action
Water—Changing States (Part 1)
Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...
Center for Learning in Action
Water – Changing States (Part 2)
Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...
Curated OER
Energy and States of Matter
Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...
Curated OER
Water and Ice
Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...
Curated OER
Disappearing Water
Students explore the water cycle. In this earth science lesson, students observe and measure water in a closed container and in an open container. Students record their observations and compare their sets of data to draw conclusions...
Polar Trec
Sea Ice Impact
The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...
Curated OER
Ice or Water?
In this ice and water worksheet, students read about the energy needed to transform ice to liquid water. Students solve 3 problems where they calculate the energy needed to melt ice given different scenarios in space.
